Title: Line of sight detector and camera
Inventor: TOKUNAGA TATSUYUKI
IPC: G02B7/28
Filed: 1994-07-26
Abstract: PURPOSE:To improve both the line of sight detecting speed of an observer and line of sight detecting precision by providing a means provided with a function to select the combination of plural photoelectric conversion elements which form a block area used in the setting of a restrictive area from different number of combinations. CONSTITUTION:The setting of the restrictive area is performed by reading out first the block with many photoelectric conversion picture elements which constitute the block. A block signal representing the minimum block signal level value is detected from them, and its coordinate is found. The coordinate (x1, y1) is located in a pupil circle, and when (x1-deltag) to (x1+deltag) are set on an X axis and (y1-deltag) to (y1+deltag) and a limiting area on a Y axis, the pupil circle is housed completely in the limiting area. By performing such processing, the pupil circle and an image P can be detected by performing the processing only in the limiting area without performing the A/D conversion and sequential processing of all picture elements in the area of an image sensor.

Title: Peak detector circuit
Inventor: KITAMURA YASUSHI
IPC: H03K5/153
Filed: 1990-07-20
Abstract: PURPOSE:To enable exact peak detection by using a high-speed operational amplifier as a buffer amplifier for driving a Schottky barrier diode and a capacitor. CONSTITUTION:The peak of a signal 1 is detected by a Schottky barrier diode 13 and a capacitor 14 and for the held peak potential, the signal 1 and the signal of dividing a voltage 2 whose peak is detected by an FET type operational amplifier 11 of high input resistance, are inputted to an operational amplifier 2 to be used as a level comparator. A transistor 17 is turned on by a signal 3 differentiating the output and discharged before the peak of the signal 1 comes. In this case, the Schottky barrier diode 13 is used to reduce a voltage drop in a regular direction as a rectifier diode and to reduce the change of a regular voltage by changing a regular current. Thus, the peak can be exactly detected while following up the reduction of an input level without being affected by the fluctuation of an input frequency.

Abstract: PURPOSE:To prevent lack of oil in an oil groove formed in a shaft fitted in a roller, by communicating the slide surface part between a bearing and a roller to the low pressure side through a communication passage so that high pressure gas leaking through the slide surface part is introduced to the low pressure side. CONSTITUTION:A communication hole 14 for communicating the slide surface part 13 between a main bearing 6 or an auxiliary bearing 7 and a roller 10 with the suction side of a cylinder 3 is formed in the inner wall of the main bearing 6 and the auxiliary bearing 7 on the cylinder side 3. During compression high pressure gas leaking through the slide surface part 13 between the main bearing 6 or the auxiliary bearing 7 and the roller 10 is led to the low pressure side through the communication passage 14. Accordingly, high pressure gas leaking through the slide surface part 13 may be prevented from flowing into the inner diameter side of the roller 10 so that lubrication oil in an oil groove 11 in a shaft 4 fitted in the roller 10 is prevented from being driven into a closed casing. Thereby it is possible to prevent lack of oil in the oil groove 11. Further, the communication passage 14 may be formed as a communication groove 16, and a gas sump in the form of a ring-like recess may be formed in the intermediate part of the passage 14.

Abstract: PURPOSE: To prevent the fall of target extraction performance when a target enters a background area. CONSTITUTION: The size I of a picture element value vector (Da, Db) whose components are the picture element values Da, Db of the picture element of an image taken by a camera 1 is calculated by a first arithmetic circuit 5, and a phase Φ is calculated by a second arithmetic circuit 6. An evaluation function generating part 7 obtains the two-dimensional histogram of the size I and the phase Φ about all the picture elements included in a background area WB in the image, and on the basis of this two-dimensional histogram, it generates an evaluation function to output evaluation values E which are the values separated distinctly from each other as the value of the background and the value of the target from the size I and the phase Φ, and sets them in an evaluation value output part 8.  At that time, the histogram H is obtained by weighting with uneven weight Z corresponding to the position (X, Y) of the picture element contained in the background area WB. The evaluation value output part 8 converts the size I and the phase Φ of the picture element value vector of each picture element contained in a target are in the image into the evaluation values by using the evaluation function, and outputs them.

Abstract: PURPOSE:To enhance the stability of a system, by discriminating whether an accident is generated in the AC system or in a power converter, based on the input/output current deviation value of the power converter and a state that excess current is generated or is not generated. CONSTITUTION:On the accident of an AC system, the waveform of a current value IIN obtained via a cyclo-converter input side current detector 22 is almost the same as that of an output side current value IOUT, and so the output  I of a comparator 19 is set to be almost zero.

On the communication failure of a cyclo-converter, the input current is set to be equal or more than the allowable value K2. In the meantime, the output current IOUT=0 is set, thereby the absolute value of the output   I of the comparator 19 is set to be equal to or more than an allowable value K1, and from the operation continuing discriminator 20, the output of main machinery emergency stop command ST is generated.

Abstract: PROBLEM TO BE SOLVED: To efficiently measure a minimum limit value which enables normal latch operation with desired precision as to the delay time of a latch signal for the data signal of a sequential circuit. SOLUTION: A short delay time T1 which disables normal latch operation and a long delay time T2 which enables the normal latch operation are set as initial values, sections T1-Tn are divided equally into (n) (n=5) parts, and (n) delay times d=t1+i.Δ (where i=0, 1, 2,..., (n-1)) are set to perform simulation. From the result of the simulation, a section where the latch operation is inverted from the normal operation to wrong operation is found and new T1 and T2 are set at both the ends of the section. The said process is repeated and when the step width Δ becomes less than desired precision ε, the delay time T2 at the point of time is outputted as a limit value.

Abstract: PURPOSE:To prevent the deterioration in characteristics due to re-writing of data by a method wherein the re-writing operation of the non-selective memory element of the memory matrix, to be constituted by a nonvolatile memory element, is prevented. CONSTITUTION:One end of a memory element 111-1n8, connected to the switches which are not turned to ON state simultaneously, is grounded through the intermediary of a normally-ON type MOS transistors (Tr) 41 and 42. When the element 111 is in a write-in state, a write-in current runs into the element 111, and a voltage is generated at both ends of the Tr111. If the drain voltage DELTAV of the Tr41, when a writing-in process is performed, is brought to DELTAV>DELTAVG for the voltage DELTAVG when a word wire is in a non-selective state, the gate and source voltage of an element 121-1n1 is turned to VGS<0, and the writing-in operation to the non-selective element is not generated. Through these procedures, the deterioration caused by the re-writing of data can be prevented.
